Peptide protocol journal

Where precision becomes a practice.
Nactara is the private dosing journal for adults running peptide protocols. Not a pharmacy. Not a marketplace. Not a coach. We do not recommend doses, suggest cycles, or interpret symptoms. Every number in the app was entered by you — Nactara just keeps it organized, calculated correctly, and quietly visible over time.
If you've been tracking protocols in spreadsheets, Notes, or memory, you already know the cost of fragmented record-keeping. A missed dose is hard to spot. A vial that ran out three days ago is hard to remember. A side effect that started two weeks ago is hard to connect to anything. Nactara solves that by giving precision a single home — one that lives privately on your device and syncs encrypted only to your own account.
WHAT YOU GET
Protocols, properly tracked.
Define a protocol with one or many compounds, set a frequency, set start and planned end dates if you have them. See "Day 23 of 90" at a glance. Watch consistency build week over week. Pause cleanly when you cycle off; archive when you're done.
Reconstitution calculator.
A clean, deterministic mg ↔ mL ↔ mcg helper. Type your vial size and bac water; get concentration and a target volume back. No suggestions, no "recommended" amounts — just arithmetic that won't fail you at six in the morning.
Vial inventory that updates itself.
Log a dose; the matching vial deducts automatically. See estimated doses left, expiration, lot number, and reconstitution date. A gold low-stock banner appears before you run out so refills don't catch you mid-protocol.
Quick-confirm logging.
Tap Mark taken on Today and confirm the details in a quick card before saving. Suggestions come from your past entries so logging stays fast without losing accuracy.
Journal that anchors the data.
Energy, mood, sleep, appetite, libido, weight, side effects, free-form notes. Every entry timestamps with your dose history so patterns surface where there used to be noise.
Photos, side by side.
Front, side, and back photos kept in encrypted storage. Compare photos at month one against month three with a single tap.
Sync between iPhone and web.
Use Nactara on your phone in the morning and on your laptop at night. Same data, same protocols, same vials. Your account is yours; export the whole archive as JSON whenever you want.
Privacy, the way it should be.
Photos and labs are encrypted on your device before upload. The server stores ciphertext. We do not sell your data, share it with insurers, run ads against it, or train models on it. There is no community feed, no leaderboard, no friend graph. Your records are your records.
A NOTE ON ETHICS
Nactara exists for adults who are already running protocols and want a better way to track them. We do not recommend doses, suggest cycles, prescribe, diagnose, or treat. We do not sell or partner with sellers of peptides, supplements, or compounded products. Nothing in the app is medical advice. Always work with a qualified clinician for any decision involving your body.
FREE TIER
Nactara is free. Start with one protocol and one vial — fully tracked, with the calculator, journal, photos, history, and automatic vial deduction all included. No countdown. No nag screens. Your data stays yours whether you ever subscribe or not.
If you pause Pro later, every record you've ever made stays visible. Additional protocols and vials become read-only — never deleted. You pick which one stays active without paying. Re-subscribe and everything writes again.
PRO SUBSCRIPTION
Pro unlocks unlimited protocols and unlimited vials, with everything you've already built carrying over. A 7-day free trial is available for first-time subscribers, full access included. Subscriptions auto-renew at the price shown at purchase; cancel any time from your iPhone Subscriptions settings. Renewal terms are shown clearly before purchase.
